` 3" Claims. This invention relates toshoes of the kindhaving cushionedheel portions. `It hasfor its principal objects to produce a shoeVhaving a simple and eflicient cushioned heel construction which will bestrong and durable and of compact design, and

to provide a simple and economical process of manufacturing suchcushioned shoes. The invention consists in the cushioned shoe and in theprocess hereinafter described and claimed.

In the accompanying drawing, which forms part of this specificationandwherein like symbols refer to like parts wherever they occur,

Fig. 2 is a perspective view of the metallic heel piece employed in theprocess of manufacturing said shoe,

Fig. 3 is a perspective view of the pad for cushioning theheel of theshoe, j

Fig. 4 is "a vertical longitudinal section through the shoe during itsprocess of manufacture, showing the position occupied by the metal heelpiece during the operation of lasting lthe upper to the insole; and lFig. 5 is a longitudinal sectional view of the finished shoe with theheel cushioning pad therein sole A, an upperB attached thereto, anoutsole C attached to the insole, and a cushioning pad D of rubber orother yielding material seated on the heel portion of the insolesubstantially flush with the inner face thereof. As shown in thedrawing, the heel seat l is formed by reducing the thickness of the heelportion of the insole an amount corresponding `substantially to thethickness of the heel pad D. This reduced thickness is brought aboutpreferably by removing the proper amount of material from the inner faceof the heel portion of the insole A. The cushioning pad is cemented orotherwise held in its seat.

In the process of manufacturing the above cushioned shoe, the insole Ais placed upon a last E with its heel seat I down. A metal plate F,having a shape and thickness corresponding to the shape anddepth,respectively, of the seat in the heel portion of the insole is theninterposed between thelast and said seat and the upper is then lasted,in accordance with common practice, to the outer face of said insole,the lasting tacks 2, which secure the rear lasting allowance of theupper to the thin heel portion of the insole, being clinched by strikingthe plate F. VAfter the lasting operation, the metal plate may beremoved and the pad D substituted therefor; or,if desired, said pad maybe secured in place after the shoe is nished. The metal plate may beprovided with prongs 3 for securing it to the insole, or it may bedesirable to secure said plate to the last or make it integraltherewith.

As shown in Fig. 5, my shoe comprises an in- (ci. 11e-"142) struction issimple, `economical and compact; it locates the cushioning pad flushwith the upper `surface of the insolein position to directly supy portthe heel of theWearer;` it permits removal and replacement of the padwithout disturbing `the other parts of the shoe and it provides a flushseat for said pad without changing the regularcontour of the insole oroutsole. The tacks,

which secure the upper to the heel portion of 10 the insole, areclinched thereon and thus cannot work loose; and the pad serves topreventsaid tacks from coming in contact with the heel of the wearer.

What I claim is:

1. A shoe comprising a, one-piece insole having a thin heel portionforming an open flatbottomed seat that extends from side to side of saidinsole and to the heel end thereof, and a cushioning member mounted onsaidthin heel portion of saidinsole, with its inner face` substantiallyflush with the `inner face of the thick portion of said insole.

2. The process of making shoes having a cushioningpad in the heelportion thereof which consists in removing the inner surface of the heelportion of an insole to form an open seat that ex- The process employedin making l the shoe is simple and economical. The metal `heel `plateserves as a support for the thin heel tends from side to side of saidinsole and to the 0 heelend thereof, placing said insole on a last,

interposing` a metal member between said last and 1 the seat in saidheel portion of said insole, se` 0 tion of an insole with a depressedseat that ex.

tends from side to side of said heel portion, placing said insole on alast, interposing a metal member between said last and the seat on saidinsole, lasting an upper to the heel portion of said insole, removingsaid metal member from said shoe` and then inserting a cushioning memberin said seat.
